摘要：
The present status of double beta decays is briefly reported. Neutrino-less double beta decays(0 nu beta beta )are sensitive to nu -masses and weak interactions beyond the standard model(SM). The present limits on the 0 nu beta beta half-lives for Ge-76, and Mo-100, Cd-116,, Te-128,Te-130, Xe-136 give upper limits of 0.3 similar to1.3 eV and 1.1 similar to4 eV, respectively, depending on the nuclear matrix elements M-0 nu. They give stringent limits on the right-handed currents; the Majoron-v couplings, and others beyond SM. Theoretical calculations and experimental evaluations for M-0 nu are discussed. Remarks on 0 nu beta beta experiments, M-0 nu evaluations, and applications of pp detectors are presented.
